I came across this during initial tests but could never reproduce it
again. Is there a root cause?

I could have reinstalled, being a new/test system and all, but a few
commands (I forgot which by now) from the mfsbsd cd did the trick.
Still, I never did get to the bottom of why it wouldn't boot.

To all others: Thanks for the input and suggestions/clarifications so far.
